If you're a sports car enthusiast, you probably live for rear-wheel drive (RWD) vehicles. Then again, if you're just looking to get to work comfortable and conveniently, you probably prefer front-wheel drive (FWD) vehicles.

What's the big difference between them?

Most BMW models are have a rear-wheel drivetrain. It makes sense for them.

BMW is a sporty luxury brand, and RWD fits that image to a T. Having powered wheels in back, and an engine up front means a RWD vehicle has a better front-to-rear weight balance for more precision handling. Then, there's the physics of…

You know your oil is important. It's the lifeblood of your car. But where does it go when you're not looking? What is it doing inside the engine?

Here's a blow-by-blow of oil's journey from Castrol.

Oil flows to the bearings, and coats the crank shaft. It cools and cleans the pistons, and undergoes enormous amounts of pressure in the valve train.

Then it returns to the sump tank to start all over again. The oil filter removes any impurities the oil picked up on its journey through the engine, so it acts as a cleaner…

Look at that Mercedes-Benz C-Class. It's regal, and a little bit grumpy, as if to tell other cars on the road to get out of its way, because its passengers are the most important. The BMW 3 Series has a similar appearance of noble severity-- like a professor or businessman who holds himself with poise, but will eviscerate you with wit if challenged.

Is it crazy to see emotions and personalities like these in a car?

Thanks to a phenomenon called Pareidolia-- false pattern recognition-- most…

Mark from Chevrolet explains why tire rotation is so important. Though you would think all of your tire treads would wear down at the same rate, they actually wear faster in certain places.

Generally, the wheels receiving power wear out faster-- particularly if you like to peel out, making tire squeal and smoke. Even if you drive conservatively, however, uneven wear is a natural fact of tire aging. On a front-wheel drive vehicle, your front tires will wear faster. The reverse goes for a rear-wheel drive vehicle, like many of our German brands favor, BMW and Mercedes-Benz.

Mythbusters is always taking on big rumors and misconceptions, and when they aren't busy making things explode, they can actually go a long way toward promoting safety.

One safety myth, started by a University of Utah study in 2006, is that talking on a cell phone impairs a driver as much as being drunk.

Any myth that involves getting drunk always tops the Mythbuster's list. It's not irresponsible drinking... it's for science.

Can the Volkswagen Beetle Dominate Rallycross? Global RallyCross is slightly less global than it sounds. All races take place within the United States-- although it is sponsored by Austrian company, Red Bull, and features international teams. The cars in rallycross must be tough as nails, but apart from the already racing-reading Subaru WRX STI, some of the names might surprise you. The most popular entrant is the Ford Fiesta ST-- heavily modified, of course. The Chevy Sonic and Hyundai Veloste
